Sure, but you should least have a basic understanding of the properties and 
characteristics of the transistors that you are using.  And especially if 
you are trying to wire up LEDs you should also get a basic understanding of 
simple LED circuits, ditto for switches and inputs.  It's not that hard and 
will make your life much easier when you start wiring up actual logic chips 
to do useful things.
